A method and access device for establishing aggregated links

Abstract

Embodiments of the present invention provide a method for establishing an aggregation link and an access device. The method includes the following steps: judging that the server is in the system installation state; withdrawing the member port from the first aggregation group and converting it to a normal Port; configure the forwarding configuration information in the configuration information of the first aggregation group on the common port; forward the request message sent by the server to the remote server during the system installation process through the common port, so that all The server completes the system installation; when the server completes the system installation, it is detected that at least two ports connected to the access device on the server initiate aggregation link negotiation, and the at least two ports connected to the server Ports and at least two ports on the server connected to the access device are added to a second aggregation group, so that link aggregation is established between the access device and the server. Improve the reliability of server deployment.

Description

technical field [0001] The present invention relates to the field of data communication, in particular to a method and an access device for establishing an aggregation link. Background technique [0002] Link aggregation is a technique used to improve high-reliability data communication between network devices. The link aggregation technology bundles multiple physical ports together to form a logical port (called an aggregation port or aggregation group), and each physical link in the aggregation link is called an aggregation member link. Multiple member links in the aggregated link send and receive traffic together, which improves the link bandwidth and improves link reliability, so that the entire link will not be interrupted due to a single physical link failure. [0003] In network application scenarios, in order to improve reliability, the server usually has multiple network cards, and multiple network cards are bundled into an aggregated link, which is connected to th...

Problems solved by technology

[0010] For solution 1, it is not feasible when the server is single-active, because one of the characteristics of the aggregated link is the balanced distribution of packets, that is, the packets on the aggregated link on the access device may randomly select a certain physical link When the server sends the installation request message, when the response message selects the physical link connected to the server’s standby network card on the access device and sends it, the message cannot be processed by the server, causing the installation to fail.

And even if the server is more active, there are risks. Some servers may require a request message to be sent from a certain network card, and the response message must be received from this network card. If it is received by another network card, the processing may fail.

However, according to the balanced characteristics of the aggregation port, the access device cannot guarantee the consistency of sending and receiving packets of the network card.

[0011] For option 2, it is feasible when the server is multi-active, but there are risks when the server is single-active, and the requirements for deployment personnel are relatively high. When the server is deployed, the active main network card must be connected to the access On the preferred port of device aggregation, if it is wrongly connected to an unselected member port, it cannot be connected to the configuration management server

And the general deployment personnel may not know which network card of the server is the main network card (there is no mark on the network card), which increases the difficulty of correct deployment
